Chris Wilson ad88d7fc6c drm/i915/fbdev: Serialise early hotplug events with async fbdev config 
As both the hotplug event and fbdev configuration run asynchronously, it
is possible for them to run concurrently. If configuration fails, we were
freeing the fbdev causing a use-after-free in the hotplug event.

In order to keep the dev_priv->ifbdev alive after failure, we have to
avoid the free and leave it empty until we unload the module (which is
less than ideal, but a necessary evil for simplicity). Then we can use
intel_fbdev_sync() to serialise the hotplug event with the configuration.
The serialisation between the two was removed in commit 934458c2c9
("Revert "drm/i915: Fix races on fbdev""), but the use after free is much
older, commit 366e39b4d2 ("drm/i915: Tear down fbdev if initialization
fails")

Fixes: 366e39b4d2 ("drm/i915: Tear down fbdev if initialization fails")
